Weight of bottlecap vs. basketweave


#1

Is there any appreciable weight difference between the two? Are there any other differences…like maybe one is 6" wide and the other is 6.5" Should I care?

What’s driving this is that I have a set of each. A local guy wants to swap me bottlecaps for my basketweaves. I’d rather have 2 sets of the same, and my impression is that the bottlecaps are lighter.

Here’s some random info I collected about spec e30 wheels a while back: http://adam.lazur.org/spece30/wheels.html (it’s probably out of date these days)

basketweaves: 14x6.5", et33, 14.3lbs
bottlecaps: 14x6", et30, 14.8lbs

The weights I got off of somewhere on the internet … so they may be questionable. I don’t have any without tires on them to do a proper comparison. Regardless, the weave is definitely .5" wider, which may help a little.

Good info, thx.

Wow that’s kinda disappointing. I thought I was saving all kinds of weight by using the Konig rewinds! But I still have my weaves as a second set :slight_smile:

You may not be saving weight, but you are gaining a lot in safety IMHO. I get a lot of peace of mind from knowing my rims are NOT 20 year old, unknown-abuse-history OEM bits.

The real hot ticket is the prototype wheel Robinson is designing on the GeegarMotorsport CAD machine. It will be rules legal (12.5 lbs, rounded to 13) and most of the mass is centered at the hub to decrease the centrifugal force of the spinning wheels. I asked him whether he was concerned about fragility. He said “I am always gapping the field, so other than lapped traffic I don’t have cars beside me.”

The fact that they’ve lasted 20 years counts for something doesn’t it? I’ve got my weaves for rain wheels (of course that would require them having rain TIRES on them, but I’ll deal with that later).

Do you search for the oldest possible bridges to drive over? :laugh:

PS - I am comfortable with older wheels as rain wheels because the side loads are minimal compared to dry racing.

Scott, look at the bolt circle of the rim and it will show the width of the rim. Basket weaves were also available that were 7" wide (IX). You may have those…and you don’t want to trade. Chuck
